- "Love doesn't exist. There is no such thing as love. Therefore, there's no sorrow."
Satan is the hidden main antagonist of Devilman Crybaby. They are an angel who was banished to Earth following a fallout with God. Under the care of Psycho Jenny, they took the form of a human boy named Ryo Asuka who had befriended a young Akira Fudo. Years later, they planned to destroy humanity by turning them against each other by revealing the presence of demons.
As Ryo Asuka, he is a lean young man with his blonde hair styled short with the back fully shaven, as well as piercing blue eyes. He is always seen in white clothes including a large overcoat.
As Satan, they are displayed as an intersex being with breasts, but male groin area. Their blonde hair grows longer and becomes wavy. Wearing no clothes, their body is covered in a veil of light. All around their body are pairs of white wings that appear on their back, the back of their feet, and the back of their head.
As Ryo Asuka, he is shown to be a young man who follows logic to its most extreme. This includes mercy killing for anything that can't be saved, as well as breaking several Japanese laws such as owning and using a gun and driving with an American driver's license to have a better survival chance. After an encounter with demons, Ryo had strove to expose demons in the best way possible to ensure humanity's survival. Ryo is also willing to kill anyone to protect Akira's secret as Devilman as he did with Koji Nagasaki and his mother.
Ryo himself did not believe in love or suffering, being rather apathetic to these feelings. His encounter with Akira and his kindly demeanor however showed his more vulnerable side as he fell in love with Akira. They had bottled up all of their frustrations of the unfortunate realities he had faced. As Ryo, he had come to grips with his grief and strove to create a better world free of the demons and regardless of the number of lives lost. But even then, he knew his actions would have dire consequences, giving Akira a choice before going any further in their plans. They only time he had ever shown fear was against the flash of light caused by God that wiped out an American Navel Fleet.
As Satan, their version of a better world is revealed to be through the lense of a spoiled child and/or a Social Darwinist, the eradication of humanity seeing them as a weak species. They also share their extreme view from their Ryo incarnation; while having no love for demons as a whole, their more simplistic lifestyles were better in their eyes seeing as their adaptations made better chances for survival. The Devilmen themselves however were seen as an unintended consequence that they planned only for Akira. Satan also revealed their love for Akira, going out of their way to prevent his death by making him strong enough.
Ryo has known Akira since early childhood and the two formed a close and valued friendship. Through Akira, Ryo came to learn about human emotions, like love and kindness. Their bond was meaningful in that it caused a previously socially withdrawn Ryo to hug and show affection to Akira. Even though Akira may have previously fallen under Ryo’s definition of “weak” he had changed this stance where it concerned him, to where he took great measures to defending Akira. Ryo continued to do this very effectively even after Akira’s assimilation with Amon.
Ryo became very attentive and insightful to Akira’s feelings, apologizing for dragging him into dangerous events for them all even though it was the only way. When Akira says he can’t remember what happened to the other party guests at the Back Sabbath party, though Ryo knows first-hand that they were all horribly killed as he watches Devilman on his laptop tearing the demons apart, he says that Akira saved the people too to spare Akira any emotional pain.
Ryo fell in love with Akira over their friendship, to the point that he spurs Akira's possession and the events of the series, in hopes of Akira being able to survive the impending battles with demons. Akira is also the only person Ryo ever cared about, as he never showed genuine concern for anyone else even his guardian Jenny, opting to kill or scapegoat them instead.
By the time they are revealed to be Satan, they revealed their actions to Akira were by their side undergone in a twisted form of affection. They were seemingly under the impression that they have both made it out of the end of the world and can finally be together, oblivious to the fact that Akira has lost everything and experienced daunting hardships. Further, the revelation that Satan instigated the collapse of civilization that resulted in said events did not sit well with Devilman. He fought with Satan until the end with the fallen angel forced to kill Devilman. Whilst contemplating the stars and previous events together, Satan realizes Akira has died. With that, <the love he has for Akira overcame the Satan aspect and Satan was forced to reflect and reverse his previous viewpoint, with Satan realizing love does exist, therefore there is sadness.
Jenny is Ryo's guardian and assistant. Always being near Ryo's side, she provides him everything he needs including food and setting up appointments with clients. This extends to her true form as the demon Psycho Jenny, assisting in Satan's plan to wipe out humanity.
As Ryo he earned a Ph.D at a young age and even taught classes. He could translate an Amazonian tribes language. He was an accomplished driver and mechanic, driving a modified sports car to keep up with a demon and using to hold his equipment. He carries an assortment of guns including a machine gun, an anti-material sniper rifle, and a pistol. Ryo also had an unnatural healing factor, able to heal and recover from serious injuries that would have crippled regular humans (although, this may be because he is an angel). He is also a keen manipulator, able to control people and events to the point of total domination.
As Satan, they are able to reincarnate at any place and time. Ever since their incarnation as a male human child, he displayed abilities such as making plants grow, killing animals with thought, causing water to materialize, create force fields, and powerful telekinetic force. Once fully revealed, they are able to fire powerful beams of light that can tear the moon in half. They can also summon lightning bolts to attack certain areas.
Satan had went against God's cold and bitter regime, later being banished to Earth in its prehistoric time. There, he encountered the demons, finding their simplistic but brutal ways interesting. However, when God had its forces attack Earth to wipe out the demons and restart from scratch, Satan and the demons would continue to thrive. In Satan's case, he would reincarnate.
Satan was born into a Peruvian native village, as the strangely white skinned and blonde haired boy. As his powers manifested, he came to be worshipped as a god to the point of sacrifice and heart offering. One day, a military unit attacked the village with Satan knocked into the ocean. He ended up floating and washed up on a dock in a village with Japanese people in it where he met the young Akira.
Growing up, Ryo never recovered his memory of what he truly is, but has nonetheless subconsciously been putting the plan of the demons reincarnation into action. Akira's kind heart intrigued but also confused Ryo as it contradicted his own beliefs. Yet they remained friends with Akira able to see through Ryo's exterior.
Ryo was later taken in by a woman named Jenny. A child prodigy, Ryo got his entire education at an early age and by the time he was a teenager became a professor and gained a substantial amount of wealth.
Ryo in Devilman Crybaby
Ryo first arrives at some docks where he defends Akira from bullies. He thinks nothing of carrying around a machine gun within his coat, and firing multiple bullets infront of their path as a warning. Akira excitedly runs up to him and they embrace before abruptly leaving together without Miki in the sports car Ryo arrived in.
Ryo explains how he is aware demons will be returning to the world and so takes Akira to an underground party. Not content with the debauchery occurring around them, Ryo amps things up a notch by attacking party goers with a broken glass bottle to help speed up the summoning of Demons. The demons do indeed arrive and the party is quickly engulfed in terror as the demons violently assimilate with the human party goers. Ryo, satisfied with this horrible turn of events manages to fend off the rapidly appearing and advancing demons with his machine gun. In the midst of the scene Ryo calls upon an "Amon" to possess Akira and continues to record the unfolding chaos on his camcorder. A large demon falls dead on top of him pinning him to the floor, but he witnesses Akira and the demon Amon successfully transforming into Devilman.
Ryo is recovering at his own penthouse after being rescued from the demons by Akira. He comes to visits to check on him. After hugging fondly, Ryo explains the fusion to him, and they travel together to find demons to test Akira’s fighting ability.
Walking on a crutch and also able to see in the dark thanks to some headgear, Ryo and Akira locate demons responsible for the murder of people. Ryo films Devilman effortlessly dispatching the three demons, before being shocked as he notices the presence of another human. He notices the infrared light from a camera meaning that this person also has recordings of Akira as Devilman. The man ignores Ryo’s requests to wait, fleeing from the demons whilst they were distracted. Panicked, Ryo turns to Akira, in the middle of tearing apart the demons, and tells him there was someone other than him filming him. Specifically he managed to record Akira changing into a devil.
